1. A second station comprising:

  • a transmitter adapted to transmit signals to a first station at a second carrier frequency modulated to represent second data signals; and

    a receiver adapted to receive signals from the first station at a first carrier frequency modulated by first data signals, and to process received signals to generate received data signals corresponding to the first data signals, wherein the receiver is adapted to;

    apply, by a frequency offset compensate block of the receiver, frequency offset compensation processing to the received signals to generate compensated received signals;

    decode, by a decode block of the receiver, the compensated received signals to generate the received data signals;

    obtain, from the received data signals, data signals representing a carrier frequency offset estimate; and

    adjust its frequency offset compensation processing of the received signals based on the data signals representing the carrier frequency offset estimate without independently generating an estimate of the carrier frequency offset between the first station and the second station.
